WTF who tells their parents about their relationships? I certainly don`t and never will, we don`t even discuss such topics. Wariidka iyo ilmaha need boundaries, waa ceeb in aad inta hooyada u tagtid ku tiraahdid "Hooyo maalmahan heblaayo ayaan ku hayaa ee ka waraan ariintas"
Now it makes sense why my brother was so reluctant to discuss his love life with my dad, it's uncomfortable.
Back to the topic, I think you should only inform your parents, if you are planning to marry the person, just to make the situation easier on the guy when he comes knocking.
